londolozi, the customcells file that you attached does not have all the information I need. Can I ask you to attach the market files as well, if you have not yet deleted the markets for which you did the import.
If you did delete them though, can you import some selections again and wait till you get this error, then send me the files below.
c:\Users\%username%\MarketFeeder Pro 7\profiles\events\
Pack this folder using any zip compressor software, and send the zipped file to me please.
I'm only asking because I still can't spot this behaviour on my computer.
By the way, if anyone else is having this, please post in this topic - you might suggest a new bit of information that will help fix this.
